Abstract

a. Appareil de commande pour chariot élévateur électrique. b. Selon l'invention, un appareil de commande comprend une source d'énergie et un interrupteur pouvant être déplacé entre une position dans laquelle il est ouvert et une position dans laquelle il est fermé. L'appareil de commande comprend des premiers moyens pour relier cet interrupteur à la source d'énergie et des seconds moyens pour changer les premiers moyens en les faisant passer d'un premier état de fonctionnement dans un second état de fonctionnement Dans le premier état, l'énergie circule de la source vers l'interrupteur tandis que dans la seconde situation, la circulation de l'énergie est bloquée. L'appareil de commande comporte des moyens pour alimenter d'une manière contrôlée les seconds moyens et pour solliciter les premiers moyens à passer de leur première condition de fonctionnement à la seconde seulement quand l'interrupteur est ouvert. c. Concerne d'une manière générale, les véhicules électriques et, plus particulièrement, les chariots élévateurs électriques.at. Control unit for electric forklift. b. According to the invention, a control apparatus comprises a power source and a switch capable of being moved between a position in which it is open and a position in which it is closed. The control apparatus comprises first means for connecting this switch to the power source and second means for changing the first means by making them pass from a first operating state to a second operating state In the first state, the energy flows from the source to the switch while in the second situation, the flow of energy is blocked. The control apparatus comprises means for supplying the second means in a controlled manner and for urging the first means to pass from their first operating condition to the second only when the switch is open. vs. Generally relates to electric vehicles and, more particularly, electric forklifts.
